新买的EE42,参照快活王2008的电路图 ,初级3X1.1X3X2,次级0.65x75,99:两档快活王标的输出有约500W,而我的反复调了3525频率,1对3205或两对输出功率都差不多,后加B772D882图腾也一样,没上过250W的,输出负荷重了,初级电流会很大,但次级却没有输出更大功率,想不明白!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!哪的问题.望好心的师傅指教!小弟感激不尽,先谢过了.500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/83/3637351257455524.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">

初级线径过大,不要超过0.8,总面积要4平方MM以上;后级线径0.5足够,大了浪费.
线应该对输出功率影响不大吧!,我个人感觉是不是磁芯不好.上不了解大功率吧!刚用EC40也试了,更差.空载无声!负200W灯就呼啸叫,<初用2.0X4X2次0.65X113T.>工作电流不稳,刚接'后级,完了电流直上5.6十A.2.3秒又烧了3205.烧怕了,求救??????????
